Types of Boilers for your Gas Heating System

What are the different types of boilers?

There are three main types of boilers that you can get in your home:

  • Combination Boiler
  • System Boiler
  • Regular Conventional Boiler

Each boiler type has advantages and disadvantages and the one that’s best for you will mostly depend on your current heating and hot water demands; AM Elements will be happy to discuss this with you at your free, no obligation quotation meeting.

If it’s time to get a new boiler then it’s a good idea to consider whether you should stick with the type of boiler system you have or swap to a different type of central heating boiler. Read our previous Blog for more information: Heating System Conversions.

What is a combination boiler (combi boiler)?

A combi boiler is a single stand-alone unit that generates all of the heating and hot water for your home. Unlike other boilers it doesn’t have a hot water tank or separate water cylinder.

How does a combi boiler work?

A combi boiler uses an integral heat exchanger to heat water directly from the cold mains. This means it’s able to provide instantaneous hot water for your home.

Because combi boilers don’t require a separate water tank, they take up less space than the other two boiler types.

What is a regular/conventional/heat only boiler?

A regular boiler (or heat only boiler or conventional boiler) only provides heating to your home. They connect to a separate hot water cylinder and a cold water storage tank.

How does a regular boiler work?

Similar to a combi boiler, a regular or conventional boiler has a heat exchanger that warms water and then uses a pump to transport the water to a water storage tank. The hot water then flows through to the radiators to heat them or into your tap when you switch them on.

The cold water is supplied to your home using the cold water tank, which is typically in the loft/attic. It fills the boiler with the help of gravity.

What is a system boiler?

A system boiler combines a boiler and separate hot water cylinder to provide heating and hot water to your home. System boilers don’t have a cold water tank and many of the components like the pumps and valves that you’ll find separate with a regular (conventional boiler) are in-built with a system boiler.

System boilers are also referred to as closed-vent or system sealed boilers.

How do system boilers work?

System boilers work with a hot water cylinder. They’re not “open vented”, which means there are no tanks in the loft and are essentially an updated version of regular boilers.

AM Elements will be happy to maintain and service any back boiler systems too and is able to conduct work and heating systems using LPG Gas as well as natural gas.
